Description
TECHNICAL FIELD
The present disclosure relates to a method of transmitting a
message associated with a vehicle from an electronic device to an
external vehicle and an electronic device thereof.
BACKGROUND
Recently, techniques have been developed in which a moving means,
such as a vehicle, communicates with other entities. The vehicle
may include a communication circuit for communication and may
transmit various information such as the speed of the vehicle, the
steering direction thereof, whether the brake thereof is operated,
etc., to other entities through the communication circuit. For
example, the vehicle may transmit information to other vehicles and
may receive information from other vehicles. Communication between
the vehicles may be referred to as vehicle to vehicle (V2V)
communication.
The vehicle may transmit information to a road side unit (RSU) or
may receive information from the RSU. Communication between the
vehicle and the RSU may be referred to as vehicle to infrastructure
(V2I) communication. The vehicle may transmit information to
electronic devices carried by pedestrians and may receive
communication signals including safety related information from the
electronic devices carried by the pedestrians. Communication
between the vehicle and the electronic device carried by the
pedestrians may be referred to as vehicle to pedestrian (V2P)
communication.
Various methods for the communication between the vehicles are
being discussed, for example, a dedicated short range communication
(DSRC) technique based on 802.11p has been proposed. In the case of
the above-described technique, a coverage capable of transmitting a
basic safety message (BSM) transmitted between the vehicles may be
limited within a certain distance (for example, 300 m to 1 km). For
example, when it is necessary to transmit a vehicle to X (V2X)
message (e.g., BSM) such as V2V, V2I, V2P, etc., to a vehicle that
is distantly remote, it is difficult for the V2X message to be
transmitted to the vehicle beyond the transmission coverage of the
BSM.
SUMMARY
Various embodiments may provide a method of generating a relayable
message and transmitting the generated relayable message to an
external vehicle when information collected in a vehicle satisfies
a designated condition, thereby efficiently transmitting a message
related to a vehicle to a remote vehicle, and an electronic method
thereof.
In order to address the aforementioned problems and/or other
problems, an electronic device according to an embodiment may
include at least one sensor; at least one communication circuit;
and a electrically connected to the at least one sensor or the at
least one communication circuit, wherein the processor is
configured to determine a relay message generation condition
associated with a vehicle based at least on data acquired from the
at least one sensor and/or the at least one communication circuit,
to generate a relay message based at least on the data acquired
from the at least one sensor and/or the at least one communication
circuit when the relay message generation condition is satisfied
based on the determination result, and to transmit the generated
relay message to an external vehicle through the at least one
communication circuit.
An electronic device according to any one of various embodiments
may include at least one communication circuit; and a processor
electrically connected to the at least one communication circuit,
wherein the processor is configured to determine whether a basic
safety message (BSM) is a relay message from information included
in the BSM received through the at least one communication circuit,
to determine whether a relay condition included in the BSM is
satisfied when the BSM is the relay message, to generate the relay
message based on the received BSM when the relay condition is
satisfied, and to transmit the generated relay message to an
external vehicle through the at least one communication
circuit.
In an operating method of an electronic device according to any one
of various embodiments, a method of transmitting a relay message
from an electronic device to an external vehicle may include
determining a relay message generation condition associated with a
vehicle based at least on data acquired from at least one sensor
and/or at least one communication circuit; generating a relay
message based at least on the data acquired from the at least one
sensor and/or the at least one communication circuit when the relay
message generation condition is satisfied based on the
determination result; and transmitting the generated relay message
to the external vehicle through the at least one communication
circuit.

for example, to a condition for retransmitting the received relay
message to another external vehicle, and may be referred to as a
`relay transmission condition`.
FIG. 1 is a block diagram illustrating an electronic device in a
network environment according to an example embodiment. Referring
to FIG. 1, an electronic device 101 may communicate with an
electronic device 102 via a first network 198 (e.g., short-range
wireless communication) in a network environment 100, or may
communicate with an electronic device 104 or a server 108 via a
second network 199 (e.g., long-range wireless communication).
According to an embodiment, the electronic device 101 may
communicate with the electronic device 104 via the server 108.
According to an embodiment, the electronic device 101 may include a
processor 120, a memory 130, an input device 150, an audio output
device 155, a display device 160, an audio module 170, a sensor
module 176, an interface 177, a haptic module 179, a camera module
180, a power management module 188, a battery 189, a communication
module 190, a subscriber identification module 196, and an antenna
module 197. In some embodiments, in the electronic device 101, at
least one of these components may be omitted or another component
may be added. In some embodiments, as in the sensor module 176
(e.g., a fingerprint sensor, an iris sensor, or an illuminance
sensor) embedded in the display device 160 (e.g., a display), some
components may be integrated and implemented.
The processor 120 may drive, for example, software (e.g., a program
140) to control at least one other components (e.g., hardware or
software components) of the electronic device 101 connected to the
processor 120, and to perform various data processing and
computations. The processor 120 may load and process commands or
data received from the other components (e.g., the sensor module
176 or the communication module 190) into a volatile memory 132,
and may store the resulting data in a non-volatile memory 134.
According to an embodiment, the processor 120 may include a main
processor 121 (e.g., central processing device or application
processor) and an auxiliary processor 123 (e.g., graphic processing
device, image signal processor, sensor hub processor, or
communication processor) which is operated independently of the
main processor, and which additionally or alternatively uses lower
power than that of the main processor 121 or is specialized in a
designated function. Here, the auxiliary processor 120 may be
separately operated from the main processor 121 or may be embedded
therein.
In this case, the auxiliary processor 123 may control at least some
of functions or states related to at least one (e.g., the display
device 160, the sensor module 176, or the communication module 190)
of the components of the electronic device 101, in place of the
main processor 121, for example, while the main processor 121 is in
an inactive (sleep) state or together with the main processor 121
while the main processor 121 is in an active (application
execution) state. According to an embodiment, the auxiliary
processor 123 (e.g., image signaling processor or communication
processor) may be implemented as some components of functionally
related other components (e.g., the camera module 180 or the
communication module 190). The memory 130 may store various pieces
of data used by at least one component (e.g., the processor 120 or
the sensor module 176) of the electronic device 101, for example,
software (e.g., the program 140) and input data or output data for
a command related to the software. The memory 130 may include the
volatile memory 132 or the non-volatile memory 134.

FIG. 2 is a diagram illustrating an electronic device, a vehicle,
and a road side unit (RSU) according to various embodiments
As illustrated in FIG. 2, at least one vehicle 220 or 240 may be
located on a road 200. An RSU 210 may be located around the road
200. The vehicle 220 may include a terminal platform 221, a vehicle
communication module (e.g., including communication circuitry) 222,
and an antenna 223, and the vehicle 240 may include a terminal
platform 241, a vehicle communication module (e.g., including
communication circuitry) 242, and an antenna 243. The vehicle 220
may include, for example, at least some of the components of the
electronic device 101 of FIG. 1. In this case, the terminal
platform 221 may include the processor (e.g., including processing
circuitry) 120, and the vehicle communication module 222 may
include the communication module (e.g., including communication
circuitry) 190. Accordingly, the fact that the vehicle 220 performs
a particular operation may include that the electronic device 101
(e.g., the processor 120) performs a particular operation, may
include that another hardware is set to perform a particular
operation according to the control of the processor 120, or may
include that an instruction that causes the processor 120 to
perform a particular operation is stored in the memory 130.
The terminal platform 221 or 241 may control various operations of
the vehicle 220 or 240 and may acquire various pieces of
information associated with the vehicle 220 or 240. For example,
the vehicle 220 or 240 may receive measurement data from various
sensors such as a speed meter (not shown), an accelerometer (not
shown), an azimuth meter (not shown), a brake detector (not shown),
a position measuring device (e.g., a global positioning system
(GPS) module) (not shown), or a road surface condition detector
(not shown). The vehicle 220 or 240 (e.g., the terminal platform
221 or 241) may generate transmission data based on the received
measurement data.
According to various embodiments, the terminal platform 221 or 241
may generate transmission data (or a message) based on information
(e.g., identification information of the vehicle 220 or 240, the
size of the vehicle 220 or 240, or capability-related information
of the vehicle 220 or 240) included in a memory (not shown) within
the vehicle 220 or 240. For example, the vehicle communication
module 222 may generate a signal corresponding to a communication
signal using the transmission data and may provide the generated
signal to the antenna 223. The antenna 223 may transmit a
communication signal 231 to a peripheral entity (e.g., the RSU 210,
a mobile terminal device 290, or another vehicle 240) using the
received signal. The communication signal 231 may include various
types of information such as the speed of the vehicle 220, the
acceleration of the vehicle 220, the azimuth direction of the
vehicle 220, whether a brake thereof is operated, the position of
the vehicle 220, road surface detection information, and the like.
For example, the vehicle 220 may transmit the transmission signal
231 defined in a wireless access in vehicular environment (WAVE)
scheme, and may use a frequency band using a designated frequency
(e.g., 5.8 GHz) as a center frequency.
According to various embodiments, the vehicle 220 may enable a
message set, a data frame, and a data element associated with an
application for implementing the WAVE scheme, to be included and
generated in a basic safety message (BSM) defined in a specific
society of automotive engineers (SAE) standard (e.g., document
J2735), and may enable the generated BSM to be included in the
communication signal 231 to transmit the resulting data. The BSM
may include information associated with the location of the vehicle
220 (e.g., latitude, longitude, altitude, or location accuracy) and
information associated with the movement thereof (e.g., speed,
heading, steering wheel angle, acceleration set, control
information (e.g., brake status), or basic information (e.g., Part
1 information) of a basic transportation means (e.g., the size of
the transportation means)), and in some cases, may further include
additional information (e.g., Part 2 information). The types of the
information included in the BSM are simply examples and may be
changed according to a change in the standard. The vehicle 220
according to various embodiments may transmit the communication
signal 231 including information having the same information type
as the information type defined in the BSM, or may transmit the
communication signal 231 including information having at least
partially different information type from the information type
defined in the BSM.
According to various embodiments, the vehicle 220 may transmit the
communication signal 231 based, for example, and without
limitation, on the transmission period, transmission frequency,
and/or transmission intensity, or the like, defined in the relevant
standard, but this is merely an example. Those skilled in the art
will readily understand that there is no limitation on transmission
conditions (e.g., transmission period, transmission frequency, or
transmission strength) of the communication signal 231. The vehicle
220 may transmit the communication signal 231 including the BSM in
a usual manner, but may enable various messages such as common
safety request (CSR), emergency vehicle alert (EVA), intersection
collision avoidance (ICA), etc., to be included in the
communication signal 231 according to various conditions and
transmit the resulting data.
According to various embodiments, the communication signal 231
transmitted by the antenna 223 may include a contextual awareness
message (CAM) according to the standard applied to the vehicle 220.
The vehicle 220 may broadcast, unicast, or multicast the
communication signal 231 to another vehicle 240, the RSU 210, or
the electronic device 101 via the antenna 223. At least one of the
terminal platform 221, the vehicle communication module 222, and
the antenna 223 included in the vehicle 220 may be referred to as
an onboard unit (OBU).
According to various embodiments, the RSU 210 may receive the
communication signal 231 from the vehicle 220 and may extract
information from the received communication signal 231. The RSU 210
may be located around the road 200 and may be disposed at a point
where the safety of pedestrians is required such as crosswalks,
traffic lights, or intersections or at a point where the risk of an
accident of the vehicle 220 is relatively high. According to
various embodiments, the RSU 210 may be disposed so that there is
no shadow area.
According to various embodiments, the RSU 210 may enable at least
one of the received information and analysis results of the
received information to be included in the communication signal 232
to broadcast the resulting data around, or may transmit the at
least one of the received information and the analysis results of
the received information to a server 201.
According to various embodiments, the server 201 may perform
management of the RSU 210, vehicle information collection, traffic
information collection, or traffic image information providence.
The RSU 210 may determine various situations (e.g., an accident
situation, a vehicle failure, a dangerous situation of a vehicle or
a pedestrian, etc.,) based on the information from the vehicle 220,
and may transmit the communication signal 232 including the
determined various situations to a vehicle (e.g., the vehicle 220
or the vehicle 240) or the mobile terminal device 290. The RSU 210
may broadcast, unicast, or multicast the communication signal 232
including at least one of identification information of the RSU
210, location information of the RSU 210, information associated
with neighboring vehicles, and information associated with
peripheral pedestrians with respect to peripheral entities. The RSU
210 may transmit warning information or the like depending on
situations. The RSU 210 may control a landmark (e.g., a traffic
light) located in a traffic zone according to the received
information.
For example, a pedestrian may be located around the road 200 while
carrying the mobile terminal device 290. According to various
embodiments, the mobile terminal device 290 may transmit, to the
vehicle 220 or 240 or the RSU 210, a communication signal 233
including information (e.g., location, speed, heading,
acceleration, path history information, information associated with
whether a pedestrian is aboard the corresponding vehicle,
pedestrian behavior information, crosswalk crossing information,
pedestrian cluster size information, work-related information,
obstacle-related information, pedestrian-related information,
pedestrian attachment entity information, or the like) acquired by
the mobile terminal device 290. The mobile terminal device 290 may
generate the communication signal 233 using information acquired
through various sensors (e.g., the sensor module 176) included
therein, information acquired through the input device 150,
information acquired through the touch circuit included in the
display device 160, or information acquired through the
communication module 190. For example, the mobile terminal device
290 may enable a personal safety message (PSM) defined in the SAE
standard (e.g., document J2735) to be included in the communication
signal 233 and may transmit the resulting data. The PSM may
include, for example, information (e.g., unavailable, pedestrian,
pedal cyclist, public safety worker, animal, etc.,) about the type
of a user.
According to various embodiments, the PSM may include, for example,
time stamp information in which a message is generated. For
example, the PSM may include message count information indicating
the number of messages generated by an object that generates the
message. The PSM may include, for example, identifier information
(e.g., fixed identifier or floating identifier) for communication.
According to various embodiments, the PSM may include information
(e.g., at least one of latitude, longitude, and altitude) about the
location of the mobile terminal device 290, and may represent the
information about the location in a unit (cm, 1/10 micro degree, or
1/10 micro degree) of, for example, the world geodetic system
(WGS), but it is not limited as long as it can represent the
location (for example, three-dimensional (3D) location).
According to various embodiments, the PSM may include accuracy
information about the location of the mobile terminal device 290.
The PSM may include, for example, information about the speed. The
PSM may include, for example, information about heading. According
to various embodiments, in the WAVE standard, the above-described
various types of information may be designated as information that
is necessarily included in the PSM, but the mobile terminal device
290 according to various embodiments may transmit the communication
signal that does not include at least some of the above-described
various types of information. For example, the information included
in the communication signal transmitted by the mobile terminal
device 290 according to various embodiments is not limited.
According to various embodiments, the PSM may include, for example,
axis-specific acceleration information. The PSM may include, for
example, information about the history of a path on which the
mobile terminal device 290 travels. The PSM may include, for
example, information about the type of propulsion (e.g., human
propelled type, animal propelled type, or motorized propelled
type). The PSM may include, for example, information about a use
state, and the information about the use state may represent
information associated with the performing operation of the mobile
terminal device 290. A parameter of the use state may include at
least one of parameters such as unavailable, other, idle, listening
to audio except for telephone, typing, calling, playing game,
reading, content viewing, and the like. The reading may be a state
in which a content having relatively small screen change over time,
such as a content of e-book or a content of web browser, is
displayed. The content viewing may be a state in which a content
such as a moving image having relatively large screen change over
time is displayed.
According to various embodiments, the mobile terminal device 290
may determine its use state based on the type of a currently
displayed content, whether an audio output is currently performed,
the type of a currently executed application, whether an input is
performed through an input device, or the like. The PSM may
include, for example, information indicating whether the mobile
terminal device 290 requests crossing a crosswalk or information
indicating that the mobile terminal device 290 is crossing. The PSM
may include, for example, information about a cluster size. The PSM
may include, for example, information about event responder types
(e.g., tow operator, emergency medical service worker, department
of transport worker, law enforcement worker, hazmat responder,
animal control worker, etc.). The PSM may include, for example,
information about activity types (e.g., police, traffic arrangement
manager, military, or emergency manager, etc.). The PSM may
include, for example, information about assist types (e.g.,
information about disabilities such as visual impairment, hearing
impairment, behavioral impairment, mental impairment, etc.). The
PSM may include, for example, information about sizing (e.g.
whether it is an adult or a child, or whether it is obscured by
surrounding features). The PSM may include, for example,
information about the attachment (e.g., a baby carriage, a cart, or
a wheelchair). According to various embodiments, the information
about the attachment may include information about the location of
a vehicle on which the mobile terminal device 290 is mounted. The
PSM may include, for example, information about the size of the
attachment. The PSM may include, for example, information about
animal types (e.g., blind guide dog). According to various
embodiments, the types of information included in the PSM are
examples and may be changed according to a change in the
standard.
The mobile terminal device 290 according to various embodiments may
transmit the communication signal 233 including information having
the same information type as the information type defined in the
PSM, or may transmit the communication signal 233 including
information having at least partially different information type
from the information type defined in the PSM. The mobile terminal
device 290 may transmit the communication signal 233 based on the
transmission period, transmission frequency, or transmission
intensity defined in the relevant standard, but this is merely an
example. Those skilled in the art will readily understand that
there is no limitation on transmission conditions (e.g.,
transmission period, transmission frequency, or transmission
strength) of the communication signal 233. The mobile terminal
device 290 may broadcast, unicast, or multicast the communication
signal 233 to the vehicle 220 or the RSU 210.
In various embodiments, when a designated condition is satisfied,
the mobile terminal device 290 may be configured to transmit the
communication signal 233. When the designated condition is
unsatisfied, the mobile terminal device 290 may not transmit the
communication signal 233, thereby saving battery power. For
example, when it is determined that the current location of the
mobile terminal device 290 is a predetermined region, the mobile
terminal device 290 may transmit the communication signal 233
including the PSM. The RSU 210 may transmit pedestrian-related
information to neighboring vehicles, and other vehicles may carry
out operations for pedestrian safety using the transmitted
pedestrian-related information. The vehicle 220 or 240 that has
received the communication signal 233 directly from the mobile
terminal device 290 may provide the information included in the
communication signal 233, or may control the traveling for
pedestrian safety based at least on the information included in the
communication signal 233.
FIG. 3 is a block diagram illustrating an electronic device
according to various embodiments.
Referring to FIG. 3, the communication module (e.g., including
communication circuitry) 190 may include a vehicle communication
module (e.g., including vehicle communication circuitry) 341, and
the vehicle communication module 341 may be connected to an antenna
342 for a vehicle communication module. The antenna 342 for the
vehicle communication module may be included, for example, in an
antenna module 197. The electronic device 101 may include a
security module (e.g., including security circuitry and/or storage
elements) 343. As described above, the electronic device 101 may be
included in the vehicle 220 or 240 or the mobile terminal device
290. The processor 120 (e.g., the main processor 121) may control
the overall operations of the electronic device 101. For example,
as instructions stored in the memory 130 are executed, at least one
piece of hardware may be controlled to perform operations
corresponding to the instructions.
According to various embodiments, the main processor 121 may
include various processing circuitry and (e.g., an application
processor (AP)) may have either a sleep state or a wake-up state.
In the sleep state, the main processor 121 may not perform any
operation, so that battery consumption by the main processor 121
may be reduced. The main processor 121 may be switched into the
wake-up state using various conditions as triggers, and may operate
in accordance with the instructions stored in the memory 130 in the
wake-up state.
According to various embodiments, the main processor 121 may
provide information associated with the traveling of other vehicles
based on information included in the communication signal received
through the communication module 190. The main processor 121 may
store, for example, information associated with the traveling of
the vehicle in the memory 130 for each piece of identification
information. When the identification information of the vehicle is
updated, the main processor 121 may associate existing
identification information with new identification information, and
may connect data corresponding to the existing identification
information to data corresponding to the new identification
information to store the resulting data in the memory 130. The main
processor 121 may acquire various types of information, such as
data from various sensors included in the sensor module 176, for
example, an acceleration sensor, a gyro sensor, a geomagnetic
sensor, etc., data from a device of measuring the coordinate
position of a GPS module, image analysis results acquired by the
camera module 180, and the like.
According to various embodiments, the main processor 121 may
control the vehicle communication module 341 and the antenna 342
for the vehicle communication module to transmit the communication
signal including the acquired information. Although not shown, a
front end module (FEM) may be connected to a space between the
vehicle communication module 341 and the antenna 342 for the
vehicle communication module. When the main processor 121 is in the
sleep state, the auxiliary processor 123 may include various
processing circuitry (e.g., the sensor hub processor) and may
perform the operation of the main processor 121 described
above.
According to various embodiments, the vehicle communication module
341 may support a WAVE communication scheme and may transmit the
communication signal including, for example, PSM or BSM, via the
antenna 342 for the vehicle communication module. In various
embodiments, the electronic device 101 may be aboard the vehicle,
or the electronic device 101 may be electrically connected to the
vehicle. For example, the vehicle communication module 341 may
transmit the communication signal including the BSM through the
antenna 342 for the vehicle communication module. The vehicle
communication module 341 may receive the communication signal
including the BSM or the PSM from other entities, and may provide
the received communication signal to the processor 120. The vehicle
communication module 341 may process the communication signal
(e.g., communication signal including the BSM from the vehicle)
received from the outside via the antenna 342 for the vehicle
communication module, and may transmit the processed communication
signal to the processor 120.
According to various embodiments, the vehicle communication module
341 may be implemented as a chip set capable of performing various
communication such as Wi-Fi communication, Bluetooth communication,
etc., in addition to WAVE communication. For example, the vehicle
communication module 341 may be implemented as a chipset capable of
performing both data processing for Wi-Fi and data processing
(e.g., data for WAVE) associated with vehicle safety. For example,
the vehicle communication module 341 may be implemented as a
chipset capable of performing both data processing for Wi-Fi and
data processing associated with vehicle safety (e.g., data for
WAVE). For example, the vehicle communication module 341 may be
implemented as a chipset designed to process data by IEEE 802.11
a/b/n/p. In addition, the antenna 342 for the vehicle communication
module may perform transmission/reception of the communication
signal for Wi-Fi and transmission/reception of the communication
signal associated with vehicle safety (e.g., communication signal
for WAVE).
According to various embodiments, the communication signal for
Wi-Fi may use a frequency band having a center frequency of a
designated frequency (e.g., 5 GHz), and the communication signal
for WAVE may use a frequency band having a center frequency of a
frequency (e.g., 5.8 GHz) having a relatively small difference with
the frequency band for Wi-Fi, so that the antenna 342 for the
vehicle communication module may perform both transmission and
reception of the two communication signals. Although the antenna
342 for the vehicle communication module is shown as being one
antenna, this is merely an example, and thus a plurality of
antennas may be implemented as required by the communication
standard. When the vehicle communication module 341 supports a
plurality of communication schemes, the vehicle communication
module 341 may be connected to the corresponding antenna for each
of a plurality of communication schemes.
According to various embodiments, the communication schemes having
similar frequencies (e.g., Wi-Fi communication in a 5 GHz band and
a WAVE communication in a 5.8 GHz) among the plurality of
communication schemes may share an antenna. The security module 343
may include various security circuitry and/or storage elements and
store information required for data processing for WAVE, and the
vehicle communication module 341 or the processor 120 may process
data for WAVE using the stored information. For example, the
security module 343 may store various types of information such as
information used for WAVE modulation/demodulation, information used
for encryption/decryption, information used for processing a
message, and the like. For example, the vehicle communication
module 341 or the processor 120 may access the security module 343
directly or indirectly.
According to various embodiments, the security module 343 may be
implemented integrally with the memory 130 or may be implemented as
different hardware, depending on the implementation. The security
module 343 may be included in the communication module 190 or the
vehicle communication module 341 depending on the implementation.
The vehicle communication module 341 may receive data from the main
processor 121 or the auxiliary processor 123 and processes the
received data to generate a signal corresponding to the
communication signal for WAVE, and may provide the generated signal
to the antenna 342 for the vehicle communication module. For
example, when the main processor 121 is in the wake-up state, the
vehicle communication module 341 may receive data from at least one
of the main processor 121 and the auxiliary processor 123. When the
main processor 121 is in the sleep state, the vehicle communication
module 341 may receive data from the auxiliary processor 123. The
auxiliary processor 123 may include at least one of a processing
circuit capable of acquiring data from at least one of sensors
(e.g., an acceleration sensor, a gyro sensor, or a geomagnetic
sensor) and a GPS module and a storage circuit capable of
temporarily or non-temporarily storing the acquired data.
According to various embodiments, the vehicle communication module
341 may include at least one of a processing circuit capable of
processing the communication signal for WAVE, a transmission
circuit capable of transmitting the communication signal, and a
reception circuit capable of receiving the communication signal.
The vehicle communication module 341 may perform scanning for
receiving the communication signal every designated period, may
analyze the result of the scanning, and may operate even when the
main processor 121 is in the sleep state. The vehicle communication
module 341 may receive the communication signal and may wake up the
main processor 121 when the data included in the communication
signal satisfies a designated condition. The vehicle communication
module 341 may include a transmission circuit for transmitting the
communication signal and a reception circuit for processing the
communication signal from other electronic devices. For example,
the electronic device 101 may selectively activate the transmission
circuit or the reception circuit. For example, the electronic
device 101 may deactivate the transmission circuit and may activate
the reception circuit to thereby scan the communication signal from
other entities even without transmitting the communication signal.
In this document, an arbitrary module for performing communication
may be referred to as a communication circuit.
According to various embodiments, the processor 120 may receive the
communication signal including the BSM or the PSM. When the main
processor 121 is in the sleep state, the auxiliary processor 123
may process the BSM or PSM included in the received communication
signal to manage the information included therein. The auxiliary
processor 123 or the vehicle communication module 341 may wake up
the main processor 121 when it is detected that the designated
condition is satisfied. The processor 120 may manage the
information for each identification information, and may associate,
when the identification information is changed, data received
together with other identification information with data received
together with the existing identification information. Meanwhile,
when the electronic device 101 is included in a means capable of
supplying sufficient power, as in the vehicle 220, the electronic
device 101 may not include the auxiliary processor 123 for a low
power mode.
According to various embodiments, the processor 120 may display
various graphical objects (e.g., a graphic user interface (GUI))
associated with vehicle safety on the display device 160. In
various embodiments, the processor 120 may display, on the display
device 160, a content indicating at least one of the movement and
location of another vehicle, which is generated based on at least a
portion of information included in the BSM received from the other
vehicle. For example, the processor 120 may display, on the display
device 160, contents corresponding to other vehicles, together with
a navigation execution screen. The audio module 170 may output
vehicle-related warning sound or the like. According to various
embodiments, the processor 120 may display, on the display device
160, information (e.g., notification message) associated with a
relay message received from another external vehicle in the form
of, for example, text or an image, or may notify a driver of the
information associated with the relay message in various methods
(e.g., sound or warning sound) through the audio module 170.
According to various embodiments, when receiving the relay message
from another external vehicle through the communication module 190,
the processor 120 may control the designated function of the
electronic device 101 (e.g., vehicle) based on the information
associated with the received relay message. For example, the
processor 120 of the electronic device 101 may perform vehicle
control such as controlling a brake based on the received relay
message, controlling the speed of the vehicle, or automatically
blinking an emergency light.
According to various embodiments, the camera module 180 may capture
an image, and the processor 120 may determine whether
transmission/reception of the communication signal for WAVE is
activated using the image received from the camera module 180. An
acceleration sensor included in the sensor module 176 may sense the
acceleration of the electronic device 101, a gyro sensor may sense
rotation information, and a geomagnetic sensor may sense
geomagnetic information. The processor 120 may enable corresponding
information to be included in the communication signal (e.g.,
communication signal including BSM or PSM) to be transmitted
through the vehicle communication module 341 by using data from
various sensors (e.g., an acceleration sensor, a gyro sensor, a
geometric sensor, etc.) or the GPS module.
FIG. 4 is a block diagram illustrating an electronic device
according to various embodiments.
Referring to FIG. 4, an electronic device 401 (e.g., the electronic
device 101 of FIG. 1, or the electronic device 290 or the vehicle
220 or 240 of FIG. 2) may include an application processor (e.g.,
including processing circuitry) (AP) 411, a display 412, an audio
module (e.g., including audio circuitry) 413, a camera 414, a PMIC
(e.g., including power management circuitry) 415, a USB interface
(e.g., including USB interface circuitry) 416, a battery 417, a
sensor hub 418, an acceleration sensor 419, a gyro sensor 420, a
geometric sensor 421, a GPS module (e.g., including GPS circuitry)
431, an antenna 432 for a GPS, an RFIC (e.g., including radio
frequency circuitry) 433, an antenna 434 for an RFIC, a
communication module (e.g., including communication circuitry) 435,
an antenna 436 for a communication module, a security module (e.g.,
including security circuitry and/or storage elements) 437, and a
memory 450.
According to various embodiments, the AP 411 (e.g., the main
processor 121) may provide control to perform the overall
operations of the electronic device 401. For example, as a command
stored in the memory 450 (e.g., the memory 130) is executed, at
least one piece of hardware may be controlled to perform an
operation corresponding to the command. The AP 411 may have either
a sleep state or a wake-up state. In the sleep state, the AP 411
may not perform any operation, and thereby battery consumption by
the AP 411 may be reduced. The AP 411 may be switched to an
automatic activation (wake-up) state using various conditions as
triggers, or may be switched to any one state of various states of
the electronic device 401. The various states may be states
associated with at least one of transmission and reception of at
least one of PSM and BSM. According to various embodiments, when
the electronic device 401 is a moving means (e.g., a vehicle), the
AP 411 may, for example, and without limitation, be a micro
controller unit (MCU) and may be configured to include at least
some functions of the MCU.
According to various embodiments, in the automatic activation
(wake-up) state, the AP 411 may operate in accordance with the
commands stored in the memory 450. The AP 411 may acquire various
types of information such as data from various sensors such as the
acceleration sensor 419, the gyro sensor 420, the geometric sensor
421, etc., data from the GPS module 431, and image analysis results
acquired by the camera 414. The AP 411 may control the
communication module 435 and the antenna 436 for the communication
module to transmit a communication signal including the acquired
information. Although not shown, an FEM may be connected to a space
between the communication module 435 and the antenna 436 for the
communication module.
According to various embodiments, the communication module 435 may
be implemented as a chipset capable of performing both data
processing for Wi-Fi and data (e.g., data for WAVE) processing
associated with vehicle safety. For example, the communication
module 435 may be implemented as a chipset designed to process data
by IEEE 802.11 a/b/n/p. For example, the antenna 436 for the
communication module may perform transmission/reception of the
communication signal for Wi-Fi and transmission/reception of the
communication signal associated with vehicle safety (e.g.,
communication signal for WAVE). For example, the communication
signal for Wi-Fi may use a frequency band having a center frequency
of 5 GHz, and the communication signal for WAVE may use a frequency
band having a center frequency of 5.8 GHz having a relatively small
difference with the frequency band for Wi-Fi, so that the antenna
436 for the communication module may perform both transmission and
reception of the two communication signals. Although the antenna
436 for the communication module is shown as being one antenna,
this is merely an example, and thus a plurality of antennas may be
implemented as required by the communication standard.
According to various embodiments, the security module 437 may store
information required for data processing for WAVE, and the
communication module 435 may process data for WAVE using the stored
information. For example, the security module 437 may store various
types of information such as information used for WAVE
modulation/demodulation, information used for
encryption/decryption, information used for processing a message,
and the like. For example, the communication module 435, the AP
411, or the sensor hub 418 may access the security module 437
directly or indirectly. The security module 437 may be implemented
integrally with the memory 450 or may be implemented as different
hardware, depending on the implementation.
According to various embodiments, the communication module 435 may
receive data from the AP 411, may process the received data, and
may generate an electrical signal corresponding to the
communication signal for WAVE to provide the generated electrical
signal to the antenna 436 for the communication module. The
communication module 435 may receive data from the sensor hub 418,
may process the received data, and may generate an electrical
signal corresponding to the communication signal for WAVE to
provide the generated electrical signal to the antenna 436 for the
communication module. For example, when the AP 411 is in an
automatic activation (wake-up) state, the communication module 435
may receive data from at least one of the AP 411 and the sensor hub
418. When the AP 411 is in a sleep state, the communication module
435 may receive data from the sensor hub 418. The sensor hub 418
(e.g., the auxiliary processor 123) may include at least one of a
processing circuit capable of acquiring and processing data from at
least one of sensors (e.g., the acceleration sensor 419, the gyro
sensor 420, the geometric sensor 421, etc.) and the GPS module 431,
and a storage circuit capable of temporarily or non-temporarily
storing the acquired and processed data.
According to various embodiments, the communication module 435 may
include at least one of a processing circuit capable of processing
the communication signal for WAVE, a transmission circuit capable
of transmitting the communication signal, and a reception circuit
capable of receiving the communication signal. The communication
module 435 may perform scanning for receiving the communication
signal every designated period, may analyze the result of the
scanning, and may operate even when the AP 411 is in the sleep
state.
According to various embodiments, the communication module 435 may
receive the communication signal and may automatically wake-up the
AP 411 when the data included in the communication signal satisfies
a designated condition. In a case in which the AP 411 is in the
sleep state in a general Wi-Fi operation, the AP 411 may be
automatically activated (woken up) when a connection has been made
even once or the communication signal is received from an access
point having a designated condition. Since information about the
designated condition or the connected access point may be updated,
information of the storage of the communication module 435 may be
changed by the AP 411 when updating is required, and the
communication module 435 may operate by the changed
information.
According to various embodiments, the communication module 435 may
include a transmission circuit for transmitting the communication
signal and a reception circuit for processing the communication
signal from another electronic device. The electronic device 101
may selectively activate the transmission circuit and the reception
circuit. For example, the communication signal from another entity
may be scanned without transmitting the communication signal by
deactivating the transmission circuit and activating the reception
circuit. In this document, an arbitrary module (e.g., the
communication module 435 or the vehicle communication module) for
performing communication may be referred to as a communication
circuit.
According to various embodiments, it is determined that the current
location of the electronic device 101 corresponds to a dangerous
area and that the electronic device 101 is located outside the
vehicle 220, the AP 411 or the sensor hub 418 may correspondingly
activate the transmission circuit of the communication module 435
and may control to transmit the communication signal (e.g.,
communication signal including PSM or BSM) including data acquired
through the activated transmission circuit.
According to various embodiments, the AP 411 or the sensor hub 418
may provide control to transmit the communication signal using at
least a portion of geographic information for a particular area.
For example, when the electronic device 401 enters a particular
area, geographic information for the particular area may be
received via an RSU (e.g., the RSU 210) or a server and may be
stored in the memory 450. In various embodiments, the memory 450
may store information about a dangerous area. The geographic
information according to various embodiments may be data
represented by a numerical value associated with at least one of a
designated latitude, longitude, and altitude, or data in the form
of an image.
According to various embodiments, when it is determined that the
location information of the electronic device 401 identified
through the GPS module 431 belongs to a designated location (for
example, a dangerous area, etc.), the AP 411 or the sensor hub 418
may control the communication module 435 to transmit the
communication signal. When the AP 411 is in the sleep state, the
sensor hub 418 may receive and store only at least a portion of the
geographic information for the particular area from the memory 450,
and may compare the stored geographic information with the current
location of the electronic device 401 identified through the GPS
module 431. The sensor hub 418 may determine whether to transmit
the communication signal based on the comparison result.
According to various embodiments, the display 412 (e.g., the
display device 160) may display various graphical objects (e.g.,
GUI) associated with vehicle safety. In various embodiments, the
display 412 may display the graphical object capable of activating
whether to transmit and receive the communication signal for WAVE,
and the AP 411 may transmit and receive the communication signal
for WAVE according to an input from a user.
According to various embodiments, the audio module 413 (e.g., the
audio module 170) may output vehicle-related warning sound or the
like. The camera 414 (e.g., the camera module 180) may capture an
image and the AP 411 may determine whether transmission and
reception of the communication signal for WAVE are activated using
the image received from the camera 414. According to various
embodiments, the PMIC 415 (e.g., the power management module 188)
may control at least one of a voltage and a current of power from
the battery 417 (e.g., the battery 189) to be a numerical value
suitable for each hardware, and may provide the resulting data.
According to various embodiments, a cable for wired power
transmission may be connected via the USB interface 416 (e.g., the
interface 177), and the electronic device 401 may receive power via
the USB interface 416 (e.g., the interface 177).
According to various embodiments, the display 421 may display
various graphic objects (e.g., graphic user interface (GUI))
associated with vehicle safety. According to various embodiments,
the AP 411 may display, on the display 412, a content indicating at
least one of the movement and location of another vehicle, which is
generated based on at least a portion of information included in
the BSM received from the other vehicle. For example, the AP 411
may display, on the display device 412, contents corresponding to
other vehicles, together with a navigation execution screen. The
audio module 413 may output vehicle-related warning sound or the
like. According to various embodiments, the AP 411 may display, on
the display device 412, information (e.g., notification message)
associated with a relay message received from another electronic
device (e.g., external vehicle) in the form of, for example, text
or an image, or may notify a driver of the information associated
with the relay message in various methods (e.g., sound or warning
sound) through the audio module 413.
According to various embodiments, when receiving the relay message
from another external vehicle through the communication module 435,
the AP 411 may control the designated function of the electronic
device 401 (e.g., vehicle) based on the information associated with
the received relay message. For example, the AP 411 of the
electronic device 401 may perform vehicle control such as
controlling a brake based on the received relay message,
controlling the speed of the vehicle, or automatically blinking an
emergency light.
According to various embodiments, the RFIC 433 may be implemented
as a chipset for, for example, data communication, and may generate
an electrical signal corresponding to a signal for data
communication based on data provided from the AP 411 to provide the
generated electrical signal to the antenna 434 for the RFIC.
According to various embodiments, the acceleration sensor 419 may
confirm the acceleration of the electronic device 401, the gyro
sensor 420 may confirm rotation information thereof, and the
geomagnetic sensor 421 may confirm geomagnetic information
thereof.
According to various embodiments, the AP 411 or the sensor hub 418
may enable corresponding information to be included in the
communication signal (e.g., communication signal including PSM or
BSM) to be transmitted through the communication module 435 by
using data from various sensors (e.g., the acceleration sensor 419,
the gyro sensor 420, the geometric sensor 421, etc.) or the GPS
module 431. In various embodiments, the electronic device 401 may
not include the sensor hub 418. In this case, the AP 411 may be
always in an automatic activation (wake-up) state or may be
automatically activated (woken up) periodically to determine
whether to transmit the communication signal.
In various embodiments, the AP 411 or the sensor hub 418 may
execute a vulnerable road user (VRU) safety application. The VRU
safety application may be an application capable of generating the
above-described BSM or PSM. The VRU safety application may
determine the location, direction, speed, and time of the
electronic device 101, or the relative position of the electronic
device 101 with other entities based on at least some of data from
the GPS module 431, data acquired from a Bluetooth low energy (BLE)
positioning system, and data collected from various sensors (e.g.,
the acceleration sensor 419, the gyro sensor 420, the geometric
sensor 421, etc.). The VRU safety application may generate the PSM
according to a detected event or may determine a point of time when
the corresponding PSM is transmitted.
In various embodiments, the AP 411 or the sensor hub 418 may select
any one of various states of the electronic device 401, and may
accordingly determine a transmission or reception mode of the PSM
or the BSM.

FIG. 5 is a diagram illustrating a transmission concept of a relay
message according to various embodiments. Referring to FIG. 5, at
least one vehicle 510 (referred to as a first vehicle for
convenience of explanation) (e.g., the electronic devices 101, 102,
and 104 of FIG. 1, the vehicles 220 and 240 of FIG. 2, and the
electronic device 401 of FIG. 4) may determine a relay message
generation condition associated with a vehicle based on data
acquired from at least one sensor or at least one communication
circuit.
According to various embodiments, when the relay message generation
condition is satisfied based on the determination result, the first
vehicle 510 may generate a relay message 511 based at least on the

communication circuit. The first vehicle 510 may transmit the
generated relay message 511 to an external vehicle through the at
least one communication circuit.
According to various embodiments, a second vehicle 520 that is an
external vehicle of the first vehicle 510 may receive the relay
message 511 transmitted from the first vehicle 510, and may display
information (e.g., notification message) associated with the
received relay message 511 on a display in the form of, for
example, text or an image or may notify a driver of the information
associated with the received relay message 511 in various methods
(e.g., sound or warning sound).
According to various embodiments, the second vehicle 520 may
receive the relay message 511 and may control a designated function
of the second vehicle 520 based on the information associated with
the received relay message 511. For example, the second vehicle 520
may perform vehicle control such as controlling a brake,

emergency light based on the received relay message 511.
The second vehicle 520 may confirm a relay condition included in
the received relay message, and may determine whether the confirmed
relay condition is satisfied. According to various embodiments,
when the relay condition is satisfied based on the determination
result, the second vehicle 520 may retransmit the received relay

message to the at least one external vehicle.
According to various embodiments, a third vehicle 530 may receive
the relay message transmitted by the second vehicle 520. The third
vehicle 530 may receive a relay message 531 transmitted from the
second vehicle 520, and may display information associated with the

predetermined distance (e.g., 1 km) or more by continuously
transmitting the vehicle-related message from at least one vehicle
to another external vehicle by the method illustrated in FIG. 5.
For example, when a coverage capable of transmitting a BSM
transmitted between vehicles is limited within a predetermined
distance (e.g., 300 m to 1 km), a message may be transmitted to a
vehicle beyond the transmission coverage of the BSM by relaying and
transmitting the message as in the method illustrated in FIG.
5.
FIG. 6 is a diagram illustrating a data format of a relay message
according to various embodiments. Referring to FIG. 6, a relay
message according to various embodiments may be included in a V2X
message 600 and may be transmitted.
For example, when the V2X message 600 includes a V2X message format
region 610 and a V2X message addition region 620 as illustrated in
FIG. 6, at least one piece of relay data of the relay message may
be included in the V2X message addition region 620 and may be
transmitted.
According to various embodiments, the relay data may be configured
to include data fields such as a type field 621, a data field 622,
a value field 623, etc. For example, the type field 621 may include
a life cycle value of the relay message and may determine whether
the relay message is transmitted or deleted according to the life
cycle. According to various embodiments, the type field 621 may
include a message relay reference value such as a movement
direction (up or down), a distance, a time, a relay frequency, or
the like.
For example, the data field 622 may include information of the
relay message (e.g., localization, real-time, and message-based
processed values received from a plurality of vehicles). According
to various embodiments, the data field 622 may include data
corresponding to immediate/local information such as a dangerous
area notification, a traffic accident warning, an emergency vehicle
warning, etc., and may include data processed based on messages
acquired from a plurality of pieces of vehicle information such as
traffic jam, "single lane driving", warning for no passing, etc.
For example, the value field 623 may include information such as a
distance from a current vehicle from a reference to which the relay
message is transmitted, a time, a calculated value of the relay
frequency, etc.
FIG. 7 is a diagram illustrating a data format of a relay message
using a BSM according to various embodiments. Referring to FIG. 7,
a relay message according to various embodiments may enable
relay-related information to be included in a BSM 700 and the
resulting data may be transmitted. For example, the BSM 700 may be
configured to include a BSM header 710 and a BSM data part 720
including a BSM data part 1 field 720a, and a BSM data part 2 field
720b. The BSM 700 may configure a message set, a data frame, and a
data element, which are associated with an application for
implementing a WAVE scheme, in a form defined in a specific SAE
standard (e.g., document J2735).
For example, the BSM data part 1 field 720a may include information
721 associated with the location of a vehicle (e.g., latitude,
longitude, altitude, or location accuracy), information 722
associated with the movement of a vehicle (e.g., speed or heading),
a steering wheel angle 723, acceleration setting, control
information (e.g., brake status), or basic information of a basic
transportation means (e.g., size of the transportation means).
According to various embodiments, the BSM data part 2 field 720b
may include at least one piece of relay data or relay-related
information constituting the relay message. For example, the BSM
data part 2 field 720b may include at least one piece of data
included in the V2X message addition region 620 of FIG. 6.
According to various embodiments, the BSM data part 2 field 720b
may include a relay condition 724, a message content 725, and
emergency vehicle location information 726 as illustrated in FIG.
7. The relay condition 724 may include distance information 724a or
direction (e.g., up or down, or heading) information 724b. Specific
examples of utilization of the above-mentioned data will be
described in greater detail below with reference to FIGS. 10 to 15.
The types of information included in the BSM 700 illustrated in
FIG. 7 are examples and may be changed according to a change in the
standard. The vehicle 220 according to various embodiments may
transmit a communication signal including information having the
same information type as the information type defined in the BSM
700, or may transmit the communication signal 233 including
information having at least partially different information type
from the information type defined in the BSM 700.

relay message to an external vehicle according to various
embodiments. Referring to FIG. 8, in operation 801, an electronic
device (e.g., the electronic device 101, 102, or 104, the vehicle
220 or 240 of FIG. 2, or the electronic device 401 of FIG. 4) may

electronic device, information about the state of a road on which
the electronic device is located, and information about weather in
an area in which the electronic device is located. According to
various embodiments, the at least one sensor may include an image
sensor included in a camera module, and the data acquired from the
at least one sensor may include state information of a road
determined from data collected through the image sensor.
According to various embodiments, the data acquired from the
communication circuit of the electronic device may include BSM data
transmitted from the at least one external vehicle adjacent to the
electronic device or PSM data transmitted from at least one
external electronic device.
In operation 803, the electronic device may determine a relay
message generation condition associated with a vehicle based at
least on information or data acquired from the at least one sensor
or the at least one communication circuit. For example, neighboring
vehicles, a road condition, and weather condition information may
be determined through the information acquired from the sensor of
the electronic device, and a plurality of V2X messages received
from a plurality of neighboring vehicles or terminals through the
communication circuit of the electronic device may be analyzed to
determine whether the plurality of V2X messages match data
corresponding to the relay message generation condition.
When the relay message generation condition is satisfied based on
the determination result in operation 805, the electronic device
may generate relay message-related information based at least on
the data acquired from the at least one sensor or the at least one
communication circuit in operation 809. According to various
embodiments, the relay message-related information may correspond
to data included in the relay data format field 620 or the BSM data
part 2 field 720b illustrated in FIG. 6 or 7.
In operation 811, the electronic device may generate a relay
message based on the generated relay message-related information.
According to various embodiments, the relay message may be composed
of the V2X message illustrated in FIG. 6 or 7 or the BSM.
In operation 813, the electronic device may transmit the generated
relay message to at least one external vehicle through the
communication circuit.
According to various embodiments, when the relay message generation
condition is not satisfied based on the determination result in
operation 805, the electronic device may generate a general V2X
message or BSM based at least on the data acquired from the at
least one sensor or the at least communication circuit and may
transmit the generated information in operation 807.
FIG. 9 is a flowchart illustrating a procedure for retransmitting a
received relay message according to various embodiments. Referring
to FIG. 9, in operation 901, an electronic device (e.g., the
electronic device 101, 102, or 104, the vehicle 220 or 240 of FIG.
2, or the electronic device 401 of FIG. 4) (e.g., a vehicle) may
receive a V2X message or a BSM transmitted from an external
vehicle, and may confirm the received message in operation 903.
In operation 905, the electronic device may display information
associated with the received V2X message or BSM on a screen through
a display, or may notify a driver of the same in various methods
(e.g., sound or warning sound). According to various embodiments,
the electronic device may receive the relay message, and may
control a designated function of the electronic device based on
information associated with the received relay message. For
example, the electronic device may perform vehicle control such as
controlling a brake based on the received relay message,
controlling the speed of the vehicle, or automatically blinking an
emergency light.
In operation 907, the electronic device may determine whether
relay-related information is included in the received V2X message
or BSM, and may determine whether the received message is a relay
message. For example, when designated relay-related information is
included in various types of messages received at the electronic
device, the received message may be determined to be the relay
message. According to various embodiments, when the message is the
relay message, the relay message may include a data field of at
least one of relay condition information, message content
information, and location information of the electronic device.
When the received message is the relay message based on the
determination result, the electronic device may confirm a relay
transmission condition (or a relay condition) included in the
received message in operation 909. According to various
embodiments, the relay condition information may include at least
one of a relay frequency, a distance, a time, and a movement
direction.
When the relay condition is satisfied based on the determination
result in operation 911, the electronic device may update the relay
message information in operation 913. For example, the electronic
device may update the relay frequency or life cycle information
included in the relay message.
In operation 915, the electronic device may retransmit the updated
relay message to at least one external vehicle through the
communication circuit.
According to various embodiments, a vehicle-related message may be
transmitted even to a vehicle separated by a long distance of a
predetermined distance (e.g., 1 km) or more by continuously
transmitting the vehicle-related message from at least one vehicle
to another external vehicle by the above-described method. For
example, when a coverage capable of transmitting a BSM transmitted
between vehicles is limited within a predetermined distance (e.g.,
300 m to 1 km), a message may be transmitted to a vehicle beyond
the transmission coverage of the BSM by relaying and transmitting
the message as in the above-described method.
A method of transmitting a relay message from an electronic device
to an external vehicle according to any one of various embodiments
may include determining a relay message generation condition
associated with a vehicle based at least on data acquired from at
least one sensor or at least one communication circuit; generating
a relay message based at least on the data acquired from the at
least one sensor or the at least one communication circuit when the
relay message generation condition is satisfied based on the
determination result; and transmitting the generated relay message
to the external vehicle through the at least one communication
circuit.
According to various embodiments, the data acquired from the at
least one sensor may include at least one of information about at
least one external vehicle adjacent to the electronic device,
information about an object loaded on the at least one external
vehicle adjacent to the electronic device, information about a
state of a road on which the electronic device is located, and
information about weather in an area in which the electronic device
is located.
According to various embodiments, the data acquired from the at
least one sensor may include state information of a road determined
from data collected through an image sensor included in a camera
module.
According to various embodiments, the data acquired from the at
least one communication circuit may include BSM data transmitted
from the at least one external vehicle adjacent to the electronic
device or PSM data transmitted from at least one external
electronic device.
According to various embodiments, the relay message may include at
least one of relay condition information about the relay message,
message content information, and location information of the
electronic device.
According to various embodiments, the relay condition information
may include at least one of a relay frequency, a distance, a time,
and a movement direction.
According to various embodiments, the relay message may be
configured using a BSM of an SAE standard.
Hereinafter, examples of various situations of transmitting a relay
message to an external vehicle according to an embodiment will be
described in greater detail with reference to FIGS. 10 to 15.
FIG. 10 is a diagram illustrating an example of a situation where a
relay message is transmitted to an external vehicle according to
various embodiments. Referring to FIG. 10, a first vehicle 1010 may
detect a sinkhole 1000 through at least one sensor (e.g., an image
sensor provided in a camera module (e.g., the camera module 180 of
FIG. 1) while traveling on a road.
The first vehicle 1010 may determine that the detected sinkhole
1000 is a dangerous situation and may determine whether the
detection of the sinkhole 1000 satisfies a predetermined relay
message generation condition (or a relay message transmission
condition).
When the detection of the sinkhole 1000 satisfies the predetermined
relay message generation condition based on the determination
result, the first vehicle 1010 may generate a relay message 1011
including related information according to the detection of the
sinkhole 1000. The first vehicle 1010 may transmit the generated
relay message 1011 to an external vehicle.
A second vehicle 1020 may receive the relay message transmitted by
the first vehicle 1010. The second vehicle 1020 may display
information associated with the received relay message on a screen
through a display. According to various embodiments, the second
vehicle 1020 may receive the relay message 1011 and may control a
designated function of the second vehicle 1020 based on the
information associated with the received relay message 1011. For
example, the second vehicle 1020 may perform vehicle control such
as controlling a brake based on the received relay message 1011,
controlling the speed of the vehicle, or automatically blinking an
emergency light.
The second vehicle 1020 may confirm a relay transmission condition
included in the received relay message, and may generate a relay
message based on the received relay message to retransmit the
generated relay message to at least one external vehicle when the
relay transmission condition is satisfied. A third vehicle 1030 may
confirm the relay message 1031 retransmitted by the second vehicle
1020 and may confirm information indicating that the sinkhole is
detected, for example, 1 km ahead.
Although FIG. 10 illustrates the detection of the sinkhole,
real-time vehicle status information such as obstacle detection,
overloading, falling object occurrence concern vehicle information,
emergency vehicle access notification, or vehicle failure
notification, real-time road information such as construction
section, real-time weather information such as fog, a sea fog,
yellow sand, or heavy rain, and the like may be generated as the
relay message and transmitted.
FIG. 11 is a diagram illustrating an example of a situation where a
relay message is transmitted to an external vehicle according to
various embodiments. Referring to FIG. 11, a first vehicle 1120 may
receive a BSM through a communication circuit from a plurality of
vehicles 1110a, 1110b, 1110c, and 1110d, which are traveling ahead
of the first vehicle 1120, while the first vehicle 1120 is
traveling on a road. The first vehicle 1120 may determine vehicle
congestion information from information included in the BSM.
The first vehicle 1120 may determine whether the vehicle congestion
information included in the BSM satisfies a predetermined relay
message generation condition (or a relay message transmission
condition).
When the vehicle congestion information satisfies the predetermined
relay message generation condition based on the determination
result, the first vehicle 1120 may generate a relay message 1121,
including the vehicle congestion information. The first vehicle
1120 may transmit the generated relay message 1121 to an external
vehicle.
The relay message 1121 transmitted by the first vehicle 1120 may be
continuously relayed and transmitted to a second vehicle 1130, a
third vehicle 1140, and a fourth vehicle 1150.
According to various embodiments, even though a transmittable
coverage of the BSM is small, a vehicle (e.g., the fourth vehicle
1150) located at a remote location may also confirm various types
of information (e.g., vehicle congestion information) by
continuously relaying and transmitting the BSM as described
above.
In FIG. 11, an example in which the vehicle congestion information
is relayed and transmitted has been described. However, information
such as a traffic accident situation such as multiple collision
accident or road collapse notification, "single lane driving"
information, a real-time traffic information status such as
specific road congestion, and the like may be generated as the
relay message and transmitted.
FIG. 12 is a diagram illustrating an example of a situation where a
relay message is transmitted to an external vehicle according to
various embodiments. Referring to FIG. 12, according to various
embodiments, a first vehicle 1210 (e.g., an ambulance) may transmit
a relay message to a plurality of vehicles 1220, 1230 and 1240,
which are traveling ahead of the first vehicle 1210, while the
first vehicle 1210 is traveling on a road, using the
above-described method.
For example, in order to notify that the first vehicle 1210 is an
emergency vehicle, the first vehicle 1210 may configure and
transmit a relay message to include relay data of which life cycle
may be set as 5 km and content is `emergency vehicle`. According to
various embodiments, the relay data may further include a current
location (e.g., location measured by a GPS) of the first vehicle
1210. According to various embodiments, the relay message may
include a V2X or a BSM.
The relay message transmitted by the first vehicle 1210 may be
transmitted to the second vehicle 1220, and the second vehicle 1220
may confirm the message received from the first vehicle 1210 and
determine whether a relay condition is satisfied. For example, the
second vehicle 1220 may calculate a relative distance from location
information of the first vehicle 1210 and location information of
the second vehicle 1220, and may determine whether the calculated
distance satisfies within the relay condition (or relay
transmission condition) (e.g., 5 km).
For example, since a distance between the second vehicle 1220 and
the first vehicle 1210 is 300 m and is within the relay condition
of 5 km, the received message may be retransmitted.
In the same manner as described above, the relay message may be
relayed and transmitted to the third vehicle 1230 and the fourth
vehicle 1240 via the second vehicle 1220.
According to various embodiments, the fourth vehicle 1240 may
calculate a relative distance from the location information of the
first vehicle 1210 and location information of the fourth vehicle
1240, and whether the calculated distance satisfies within the
relay condition (or relay transmission condition) (e.g., 5 km) may
be determined. For example, when a distance between the fourth
vehicle 1240 and the first vehicle 1210 exceeds the relay condition
of 5 km, the received relay message may not be retransmitted due to
life time extinction.
According to various embodiments, as illustrated in FIG. 12, the
BSM may be immediately transmitted by including locality-based
information such as accident occurrence, emergency vehicle
dispatch, weather information, sinkholes, and the like in the relay
data. As described above, whether each piece of relay data is
retransmitted may be determined by a life time defined according to
the types, and therefore each piece of relay data may be destroyed
when the life time expires.
FIG. 13 is a diagram illustrating an example of a situation where a
relay message is transmitted to an external vehicle according to
various embodiments. Referring to FIG. 13, according to various
embodiments, when vehicle congestion information is determined
based on a plurality of BSMs received from a plurality of pieces of
vehicle information, a relay message may be transmitted by
including a reference setting value for a direction and a distance
and data information in relay data. For example, each vehicle may
calculate its own vehicle direction/distance and may transmit the
received relay message (e.g., BSM) only when a corresponding
condition is satisfied.
According to various embodiments, a first vehicle 1320 may receive
the BSM from a plurality of vehicles 1310a, 1310b, 1310c, and
1310d, which are traveling ahead of the first vehicle 1320, through
a communication circuit while the first vehicle 1320 is traveling
on a road. The first vehicle 1320 may determine vehicle congestion
information from information included in the BSM.
The first vehicle 1320 may determine whether the vehicle congestion
information included in the BSM satisfies a predetermined relay
message generation condition (or a relay message transmission
condition).
When the vehicle congestion information satisfies the relay message
generation condition based on the determination result, the first
vehicle 1320 may generate a relay message, including the vehicle
congestion information. The first vehicle 1320 may transmit the
generated relay message to an external vehicle. According to
various embodiments, the relay message may further include distance
and direction (e.g., up or down) information (e.g., "down by a
distance of 1.3 km"), relay message content (e.g., congestion), and
a value field (500 m northeast) as a relay condition.
The relay message transmitted by the first vehicle 1320 may be
continuously relayed and transmitted to the second vehicle 1330 and
the third vehicle 1340 which are traveling in the same direction
(e.g., down direction) as that of the first vehicle 1320. According
to various embodiments, the second vehicle 1330 may receive the
relay message from the first vehicle 1320, may confirm relay
condition information included in the relay message, and may
retransmit the received relay message because the relay
transmission condition is satisfied. According to various
embodiments, the second vehicle 1330 may update and retransmit
relay-related information included in the relay message received
from the first vehicle 1320, when the relay message is
retransmitted.
According to various embodiments, the third vehicle 1340 may
receive the relay message from the second vehicle 1330, may confirm
the relay condition information included in the relay message, and
may stop the retransmission of the received relay message when the
relay transmission condition is not satisfied.
According to various embodiments, the relay message transmitted by
the first vehicle 1320 may be also transmitted to at least one
vehicle 1350a, 1350b, 1350c, 1350d, 1350e, 1350f which is traveling
in a direction (e.g., up direction) opposite the direction of the
first vehicle 1320. The at least one vehicle 1350a to 1350f which
is traveling in the direction (e.g., up direction) opposite the
direction of the first vehicle 1320 may confirm direction
information included in the received relay message, and may
determine that the relay condition is not satisfied because the at
least one vehicle 1350a to 1350f is traveling in the direction
opposite the direction of the first vehicle 1320. Based on the
determination result, the at least one vehicle 1350a to 1350f which
is traveling in the direction (e.g., up direction) opposite the
direction of the first vehicle 1320 may not retransmit the received
relay message. According to various embodiments, the at least one
vehicle 1350a to 1350f which is traveling in the direction (e.g.,
up direction) opposite the direction of the first vehicle 1320 may
control to display or not to display information associated with
the received relay message through a display or the like.
FIG. 14 is a diagram illustrating an example of a situation where a
relay message is transmitted to an external vehicle according to
various embodiments. Referring to FIG. 14, when an accident occurs
while the first vehicle 1410 is traveling on a road, an accident
state may be determined through at least one sensor.
The first vehicle 1410 may determine that the determined accident
state is a dangerous situation and may determine whether the relay
message generation condition (or relay message transmission
condition) is satisfied.
When the relay message generation condition is satisfied based on
the determination result, the first vehicle 1410 may generate a
relay message, including the accident-related information. The
first vehicle 1410 may transmit the generated relay message to an
external vehicle.
As illustrated in FIG. 14, a plurality of vehicles 1421, 1422, and
1423 located within a BSM reach range of an accident vehicle may
simultaneously receive the relay message transmitted by the first
vehicle 1410.
When the plurality of vehicles (the second vehicle 1421, the third
vehicle 1422, and the fourth vehicle 1423) simultaneously receive
the relay message and simultaneously retransmit the received relay
message, the number of messages to be transmitted may be increased
so that a case in which congestion of a wireless channel is
unnecessarily increased may occur.
According to various embodiments, in order to solve this problem, a
message may be relayed and transmitted by applying a retransmission
method using a random transmission time or a BSM coverage-based
retransmission method.
According to the retransmission method using the random
transmission time, vehicles having received the relay message
having a specific signal strength or less may respectively set the
random transmission time to wait for transmission. When a vehicle
with the highest random transmission time transmits the
corresponding message, other vehicles may stop message
transmission.
For example, as illustrated in FIG. 14, the plurality of vehicles
1421, 1422, and 1423 located within the BSM reach range of the
accident vehicle may simultaneously receive the relay message
received by the first vehicle 1410, and each of the plurality of
vehicles may randomly set a transmission time for message
retransmission. Assuming that the transmission time of the second
vehicle 1421 among the plurality of vehicles is the fastest, when
the second vehicle 1421 retransmits the relay message, the third
vehicle 1422 and the fourth vehicle 1423 located in the vicinity of
the second vehicle 1421 may receive the corresponding relay
message. The third vehicle 1422 and the fourth vehicle 1423 located
in the vicinity of the second vehicle 1421 may detect that the
received relay message has already been retransmitted by another
neighboring vehicle (second vehicle 1421) to stop the message
retransmission desired to be performed, and thereby only the second
vehicle 1421 may retransmit the relay message. A fifth vehicle 1430
may receive the relay message transmitted by the second vehicle
1421.
According to various embodiments, according to the BSM
coverage-based retransmission method, a vehicle (e.g., the third
vehicle 1422 in FIG. 14) located farthest within the BSM reach
range may retransmit the relay message.
FIG. 15 is a diagram illustrating an example of a situation where a
relay message is transmitted to an external vehicle according to
various embodiments. Referring to FIG. 15, according to various
embodiments, a first vehicle 1510 (e.g., an ambulance) may transmit
a relay message to a plurality of vehicles 1520, 1530, and 1540,
which are traveling ahead of the first vehicle 1510, using the
above-described method while the first vehicle 1510 is traveling on
a road.
For example, in order to notify that the first vehicle 1510 is an
emergency vehicle, the first vehicle 1510 may configure and
transmit the relay message to include relay data of which relay
condition is set as a distance of 2 km, direction is set as an up
direction, and content is set as `emergency notification`.
According to various embodiments, the relay data may further
include a current location (e.g., location measured by a GPS)
(emergency vehicle GPS) of the first vehicle 1510. According to
various embodiments, the relay message may include a V2X or a
BSM.
The relay message transmitted by the first vehicle 1510 may be
transmitted to the second vehicle 1520, the third vehicle 1530, and
the fourth vehicle 1540, and the second vehicle 1520 may confirm a
message received from the first vehicle 1510 and determine whether
a relay condition is satisfied. For example, the second vehicle
1520 may calculate a relative distance from location information of
the first vehicle 1510 and location information of the second
vehicle 1520, and may determine whether the calculated distance
satisfies within the relay condition (or relay transmission
condition) (e.g., 2 km). In addition, whether a traveling direction
of the second vehicle 1520 is an up direction according to the
relay condition may be further determined.
For example, since a distance between the second vehicle 1520 and
the first vehicle 1510 is within the relay condition of 2 km and
the traveling direction is the up direction, the received message
may be retransmitted.
In the same manner as described above, the relay message may be
relayed and transmitted to the third vehicle 1530 via the second
vehicle 1520.
According to various embodiments, a fifth vehicle 1550 and a sixth
vehicle 1560 may calculate a relative distance from the location
information of the first vehicle 1510 and location information of
vehicles 1550 and 1560, and may determine whether the calculated
distance satisfies within the relay condition (or relay
transmission condition) (e.g., 2 km). For example, the distance
between the fifth vehicle 1550 or the sixth vehicle 1560 and the
first vehicle 1510 is within the relay condition of 2 km, but the
condition for the traveling direction is not satisfied as shown in
FIG. 15, and thereby the relay message may not be
retransmitted.

according to various embodiments. According to an embodiment, the
program 1640 may include an operating system (OS) 1642 for

and an external electronic device. The information exchange
application may include, for example, a notification relay
application for transmitting designated information (e.g., calls,
messages, or alarms) to an external electronic device, or a device
management application for managing an external electronic device.
The notification relay application may transmit notification
